Outgoing CDOT Comm. Gia Biagi speaks during a news conference in April 2021. 

A group of transportation advocacy groups on Monday sent Mayor Brandon Johnson an open letter detailing the characteristics they want to see in a new leader for the Chicago Department of Transportation (CDOT). 

The letter signed by 16 groups, including Active Transportation Alliance, Sierra Club Chicago, Access Living and Better Streets Chicago, comes one week after CDOT Comm. Gia Biagi announced that Friday will be her last day helming the department.
